TimePower TP582 Copper Strip Corrosion Tester

Overview

The TimePower TP582 Copper Strip Corrosion Tester is a precision-engineered instrument designed to evaluate the corrosive tendency of petroleum products toward copper surfaces under standardized thermal exposure conditions. It operates in strict accordance with internationally recognized test methods—including ASTM D130, GB/T 5096, GB/T 7327, SH/T 0232, and SH/T 0023—to quantify corrosion rating based on visual assessment of standardized copper strips after immersion and heating. The instrument employs a thermostatically controlled metal bath system, eliminating reliance on oil or water baths and ensuring rapid thermal equilibration, minimal temperature gradient across sample wells, and high reproducibility between runs. Its architecture supports routine quality control in refinery laboratories, fuel specification compliance verification, and R&D screening of additive packages where copper compatibility is critical—such as in aviation turbine fuels, gasoline blends, diesel distillates, lubricating oils, and solvent naphthas.

Key Features

• Integrated metal-block heating bath with PID-based temperature regulation for stable, uniform thermal environment across all sample wells
• Independent digital LED displays for real-time monitoring of both setpoint and actual bath temperature and elapsed test time
• Programmable timing function (1 minute to 24 hours) with audible alarm upon test completion
• Self-diagnostic firmware that continuously monitors sensor integrity, heater status, and thermal stability
• Four dedicated sample wells accommodating ASTM D130-compliant copper strip holders; scalable configuration supports up to 12 strips per test cycle via sequential loading
• Robust mechanical design with compact footprint (420 × 315 × 550 mm) and optimized thermal insulation to minimize ambient heat loss and energy consumption
• Compliance-ready operation: temperature and time logging capability aligns with internal laboratory documentation requirements for GLP-aligned workflows

Sample Compatibility & Compliance

The TP582 is validated for use with hydrocarbon-based samples meeting defined volatility limits—specifically those with Reid Vapor Pressure (RVP) ≤124 kPa (equivalent to ~930 mmHg or ~30 inHg)—including aviation gasoline (AVGAS), jet fuel (Jet A/A-1), motor gasoline, natural gasoline, kerosene-type solvents, light and middle distillate fuels (e.g., EN 590 diesel), and lubricant base stocks. All testing procedures adhere to the specimen preparation, immersion duration, temperature ramping, and post-test evaluation protocols specified in ASTM D130 and its harmonized national equivalents. The instrument’s temperature accuracy (±1 °C) and temporal resolution (1-minute increments) satisfy the metrological requirements for pass/fail determination against ASTM D130 corrosion rating scales (from 1a—light straw—to 4c—jet black and heavily tarnished). No modifications to standard copper strip dimensions (75 × 12.5 × 1.5 mm) or polishing protocol are required.

Software & Data Management

The TP582 operates as a standalone hardware platform without embedded PC software or network connectivity. All operational parameters—including set temperature, start time, duration, and final bath temperature—are manually configured and displayed locally via dual LED modules. While it does not generate electronic audit trails or export raw data files, its deterministic control logic and stable thermal performance enable full traceability when paired with laboratory notebook entries or LIMS-integrated manual data capture. For regulated environments operating under FDA 21 CFR Part 11 or ISO/IEC 17025 frameworks, users may implement procedural controls—such as dual-operator verification of settings and timestamped logbook recording—to fulfill documentation requirements for method validation and equipment qualification (IQ/OQ).

Applications

• Refinery QC labs performing routine corrosion screening of finished fuels prior to shipment
• Fuel additive development laboratories assessing synergistic or antagonistic effects of sulfur scavengers, metal deactivators, and antioxidant formulations
• Third-party testing facilities conducting certified conformance testing per ASTM, GB, or SH standards
• Aviation maintenance organizations verifying fuel integrity during storage and handling audits
• Research institutes investigating copper-catalyzed oxidation pathways in hydrocarbon systems
• Contract laboratories supporting regulatory submissions requiring documented corrosion test evidence

FAQ

Does the TP582 support automated data export or USB connectivity?
No. The instrument features only local LED display and manual control interface; no serial, USB, or Ethernet ports are included.

Can the unit be used for tests requiring temperatures above 100 °C?
No. The maximum rated temperature is 100 °C, consistent with the upper limit specified in ASTM D130 and related standards.

Is calibration certificate provided with delivery?
The unit ships with factory calibration verification documentation for the Pt100 sensor and timer circuit. Full ISO/IEC 17025-accredited calibration requires external service by an accredited provider.

What maintenance is required for long-term reliability?
Periodic inspection of heater contacts, cleaning of metal bath surface with non-abrasive solvent, and verification of copper strip holder alignment every 500 test cycles are recommended.

Are replacement copper strips and polishing kits available from TimePower?
TimePower supplies ASTM-compliant copper strips (ASTM B152 Grade C10200, oxygen-free, 99.99% Cu) and standardized abrasive papers (e.g., 120-grit and 240-grit silicon carbide) as optional accessories.
